I may have missed something, but I haven't seen Doors say anything particularly offensive. Although I'm wary of perpetuating this trail, suggesting stopping SUPPORTING a political system that can't work is not quite suggesting you change your beliefs. It could be interpretted that way, but then again holding any completely impractical ideal isn't necessarily a great idea. But then hope may be good, as may be dreaming, and hey, communism might work.
Has anyone actually looked at the link Wuggly Blight posted by the way (not that I want to stray on topic or anything).
